POWER-DRIVEN RAZOR.

Application filed February 2, 1923. Serial No. 616,550.

To all whom it may concern.

Be it known that I, BARTOLO PARATORE, a citizen of the United States,residing at Johnstown, in the county of Cambria and State ofPennsylvania, have invented new and useful Improvements in Power-DrivenRazors, of which the following is a specification.

This invention relates to razors and has for its object the 'rovision ofa razor having a movable bla e protracted and retracted rapidly withrespect 'to a protectivepasing by means of a cam driven from anysuitable power device.

An important object is the provision of a device of this character inwhich the major portion of the blade is protected by a cover plate whichis removable to facilitate cleanin the parts.

Anot er object is the provision of a device of this character which willgive a very smooth shave, which will be positive and rapid in operation,efiicient and durable in service and a general improvement in the art. a

With the above and other objects and ad vantages in view the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed and illustrated in the accompanying drawings, inwhich:

Figure 1 is a side elevation of the device,

Figure 2 is an ed eLvieW thereof, Figure 3 is an en elevation,

Figure 4 1s a cross sectional view taken through the blade and easing,

Figure 5 is a perspective view of one'end of the blade, and I Figure 6is a detail elevation of the operating shaft.

Referring more particularly to the drawings I have shown my device ascomprisin an elongated supporting member 10 whic may be constructed ofmetal or any other desired material and which may be of any otherconvenient size. One end of this member 10 is formed as ahandle 11 andis preferably shaped for convenient engagement within the operators handwhile the other end 12 constitutes one section of the casing fortheblade 13 which is preferably of elonated, rectangular shape and which issemi-cylindrical recess 14, the recess being formed by stamping theblade prior to tempering thereof.

orined. near one edge with a substantially The blade is ordinarilyprotected by a cover plate 15 which is provided at one edge with pins 16slidably engaged within holes 17 in the back or edge of the casingportion 12 of the supporting member 10. Thls cover plate protects theblade and is held in position by a detachable or movable catch 18carried by the support 10.

- Journaled longitudinally within the member 10, which is hereillustrated as having its handle portion either hollow or of U shape incross section, is a shaft 19 having one end formed with a species ofchuck or socket 20 for connection with the ultimate element of aflexible drive shaft, not shown, which is power driven by any. suitablemeans. The other end portion of this shaft 19 carries accam 21 which maybe formed integrally thereon or which may be formed separately andsecured thereto. The extremity '22 of the shaft is journaled within abearing hole 23 in the outer end of the support 10 and the cam portion21 is engaged within the recess 14' in the blade.

In the operation it will be seen that when the shaft 19 is rotated bywhatever "flexible drive connection is rovided, the engagement of thecam 21 within the recess 14: of the blade will cause the blade to bereciprocated laterally, the cutting. edge being extended beyond andretracted within the edge of the casing alternately, so as to have anefiicient cutting action. Whenever it is necessary to clean the parts,the catch 18 is released to permit removal of the cover 15 andthe partsmay then be easily disassembled and scalded or otherwise treated toefi'ect cleaning and sterilization so that the device can be kept inproper sanitary condition.

From the foregoing description and a study of the drawings it will beapparent that I have thus provided a simply constructed andconsequentlyinexpensive power driven razor which will be easy to handle,

rapid in action, and a general improvement in the art. 4

While I have shown and described the preferred embodiment of theinvention it is of course to be understood that I reserve the right tomake such changes in the form, construction and arran ement of arts aswill not depart from t e spirit 0 the in vention or the scope of thesubjoined claims.

Having thus. described my invention 1 claim: 1. A power driven safetyrazor comprising an elongated handle having one end prolonged and formedto define a casing section, a removable cover engaged against and matingwith said prolongation to complete casing and formed with oppositeofiset portions, -certain ofl set portions guiding the blade withrespect to the shaft and the other ofiset portion bearing conforminglupon the cam, the blade projecting throng a slot between saidprolongation and the cover.

2. In a safety razor, a casin having a removable cover and prolonged todefine a eccentric, and a blade slidable transversely of the casing andgrojeotable beyond one edge thereof,-the bla e having its inner edportidn formed with a semi-cylindrical ou'twardly pressed portion and aair of beering strips extending opposite y from said semi-cylindricalportion, said bearing strips enga mg against said shafts, and saidsemicylin rical portion conformingly engaging upon said eccentric.

In testimony whereof I afix'my signature.
